Ways to leverage the equity in a 3 unit building without going the traditional route

[Michael Fradette]

Hi Team, 

Looking for feedback and ideas on how to leverage equity in a 3 unit building without doing a cash out refinance? The rate on my mortgage is amazing (low 3'%) and have no plans to lose that. Is anyone savvy on alternative/ creative ways to pull out/ borrow against equity in order to use the capital toward another project? 

Thanks all! 
Mike
